A sort of direct modeling inside Moi! ;)

it's also very useful in the Boolean function Isect (history enabled by default)

Modify any section (or both) will modify the target form!

At any moment of the session till the target form is not modified by any other function!

Here only the circle is modified! But you can also modify the square! ;)



More elaborated! :)

Hi Pilou,

You are doing that in MoI?

How?

Thanks.

The animation ? WIth a simple free Gif recorder : GifCam http://blog.bahraniapps.com/gifcam/

The volume itself in MOI ? Of course yes!
Draw your profil (s) 1 Minimum to the infinite! :)
Choose any combinaison of profils (2 familly of selectioned profils) you want following the result wanted...then Press Boolean Isect!

Click profil(s) then Press Isect

You can use Show Points for easy help for modify a profil...
Profil(s) must be "Plane" but not obligatory perpendicular or parallal to the volume!

Better to have curves closed else the Isect volume will be just a "Surface"

Draw profils before anythings
Then click rofils then press Isect!!!

If you draw a volume first you will have only one "cut" and no possibility to modify "profil(s)" !

Volume must be result of an Isect of several profils ! ;)

“”””””””” So, if I have something that isn't a basic solid, but a complex solid and I need to apply a draught angle for mould release, I have to throws away everything and start from scratch to do so?”””””””””

In MoI, if i wanted a cube with a draft angle, i wouldn't “draw a cube and then edit the draft by dragging/moving edges”. I would draw a square and then extrude it using the draft/angle option.

So Michael answered he has plans to add in some direct modeling!!!

For now, you must model it in.

Hi Buk,

There's no quick and easy command to add draft. One way to do it is by replacing the extruded faces with a sweep of a line that's tilted at the draft angle. Gets into surface modelling territory though.

To do it with solid modelling the best route is probably Construct > Extrude > Tapered and then Boolean > Diff/Union

Hi Pilou,

I am doing something wrong.

I drew a plane.

I drew another plane at right angles to the first.

I clicked Boolean Intersect.

Nothing happened - no solid appeared where the two planes would intersect, if projected.

What have I overlooked?

Thanks.

Hi Frederick,

re:

Try drawing a rectangle curve instead of a plane surface.

Planar curves are automatically extruded into solids with booleans, planar surfaces like you constructed are not.

Hi Michael,

Pilou referenced "planes" and I took that literally.

It works just fine now.

I had no idea MoI could do that - it could be wonderfully useful.

Thanks.

Don't undertstand your problem...

HI Pilou,

Michael got me sorted out.

I was using planes, not planar curves, as you were using.

All is good.
